To all hom it mag concern:

Be it known that we,1,RoBERrM.' CA'UFE- MAN-and ,WELLINGLEON Bns'r,citizens of the United States, residing at Centerville, in the county ofSt. Joseph and State 0% Michigan,

following is a specification.-

.aware that milk will not sour as quicklyiuanj open vessel as in ahermetically sealed con- 'tainer, and one of the objects of ourinvention is to improve existing conditions mania nation and arran ementof parts hereinafter more fully described, illustrated in. the'ac- Thisinvention relates to milk jar closuresj Dairymen, milk dealersand'others'are fest in the handling of milk hermetically sealed inbottles or jars ,in which the milk isserved to consumers." 1 I Anotherobject of the invention resides in the provision of a closureof thenature stated embodying 'such' characteristics that it will permit ofthe ingress of air into the container to commingle with the milk butprevent the admission of insects or other im purities. A still furtherobject. is to provide a 010 sure composed of fibrous material and animpervious material, the latter adhering to portions of the formerand'not to, other port-ions thereof so that the impervious material will.not hinder the filtering of the air through the closure.

With the above and other objects in view they present invention consistsin the combicompanying drawings, and particularly pointed out intheappended claims,-it being 7 understood that changes may be made inthe form, proportion, size and-minor details Without departing from-thespirit or sacrificing any of the advantages of the invention.

In the drawings-Figure 1 is a sectional view of a portion of a bottle orjar, illustrating the application of our invention. Fig. 2 is a planview .of the closure.

Referring now to the accompanying drawings to explain thecharacteristics of our invention in detail, the reference character 1indicates the neck portion ef a bottle or jar provided with an annularinternal shoulder 2 for the support of our impraved closure.

struction, and our closure is particularly adapted. to the bottles andjars now in common use.

The-closiire is preferably composed of a fibrous disk 3 and animpervious disk 4, the former being 'of any suitable character or' 2fabric and the latter being of any suitable impervious material,preferably paraffin,

"Thus the fibrous disk is coated on' one side with an impervioussubstance, and in use,' the coated side of thedisk is preferably exposedto contact by the milk because-it will not absorb the milk splashedagainst it in the handling of the jars or bottles. The

coating has the further function of stifienin the fibrous material. I

ihe fibrous material if used alone, would permit of the ingress of airinto the jar and also prevent'the ingress of insects or other foreignmatter likely to contaminate the milk; and in order that the paraffindisk coating will not interfere with the admission of air into the jarthrough the fibrous material, we prefer to leave portions of the fibrousdisk 'uncoated, thereby providing openings 5 in the imperviouscoating'to permit the air to filter through the fibrous material and theopenings 5, and enter the container to preserve the milk.

In the manufacture of our improved closure the machine for making thesame may have a die constructed to cut the disks out f RDBERT M.CAUFFMAN. .WELLINGTON BEST.
